New ways of building are being tried outeverywhere. There are many new shows to watch!

In England, I saw a 17-story building maderight on the ground. First, the workers dug a deep hole. They build thebasement. This word was the same as on any building. From then on, the work wasnot the same.

On the ground, the men set 40 big jacks(千斤顶)。Youknow what a car jack does. It lifts a car. These big jacks were to lift eachfloor of the building. On top of the 40 jacks, the men first built a roof. Yes,the roof of the building!

What next? The jacks lifted the floor onestory high. The builders worked on this floor. It was not the bottom floor. Itwas on the ground then. But it was going to be floor 17. The jacks lifted floor17.Under it, the workers built floor 16.They built it right on the ground, too.

When floor 16 was done, the jacks lifted it.Under floor 16, the men built floor 15.And so it went. The bottom floor of thebuilding was made last.

The work went quickly. Under the roof, theman worked even in rain or snow. They didn’t need to climb to high places. Andtrucks brought things right to them.

It took only one man to work the jacks, Hejust pushed a button. right away, the jacks began to lift.

In the United States, also, some builders usebig jacks. But the jacks are above the floors, not under them. The floors aremade of concrete(混凝土)。Theyare made on the ground, one on top of another. Strong posts run through them.

At first, the floors look like a big pile ofpancakes, as the picture shows. Then jacks at the top of the posts lift eachfloor into place. The top floor makes the roof.

In Texas, I saw a roof made in a new way. Ahelicopter flew over the building, again and again. Each time, it stopped toput a piece of the roof into place. The helicopter was like a bird building anest.

What a funny way to make a roof! But thehelicopter built in one morning. To make a roof like this, it take weeks.
